🌟 Summary

Streamlining output directory management for saving and cropping operations in YOLOv5 detection results.

📊 Key Changes

• Altered the save method by introducing an exist_ok parameter, controlling the overwrite behavior for existing directories.
• Updated the crop method with a new exist_ok parameter to match the save method's behavior.

🎯 Purpose & Impact

• 💾 Enhanced Customization: Users now have more control over how the results are saved, particularly when dealing with existing directories.
• 🔄 Consistency Across Methods: Both save and crop methods now share a similar interface for directory handling, making the API more uniform.
• 🛠️ Reduction of Default Overwrites: By default, directories won't be overwritten, reducing the risk of unintentional data loss or confusion.
• 🤖 Potential Automation Enhancements: With the explicit exist_ok parameter, automation scripts that leverage these methods can be more precise and safer.
